CORDER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 250,062, dated November 29, 1881.

Application filed May 11, 1881.

Be it known that I, EDGAR D. FELLOWS, of Berlin, in the county of Rensselaer and State of New York, have invented a new and useful Improvement in Gorders for Sewing-Machines, which improvement is fully set forth in the following specification.

This invention relates to the sewing-machine attachments known as corders, for laying or delivering a cord between or upon fabrics in position to be secured by a seam alongside of the cord, and particularly to those which have guides for folding a strip or piece of cloth, combined with a device arranged to deliver the cord into the fold of the strip or piece.

Such corders have heretofore been constructed generally with a tube or eye formed in rigid or non-elastic material, and of a diameter equal to the size of the cord to be delivered, and they have been objectionable, because a separate corder has been required for each size of cord, and also because great smoothness and uniformity in the cord (when this is of proper size) have been necessary to successful operation.

The present invention has for its object to obviate these objections and to produce an attachment of the kind referred to which can be used with cords of different sizes, and which will inclose the cord in the folded material in the most perfect manner, notwithstanding inequalities orirregularities in said cord.

Heretoi'ore in braiders which simply deliver a braid or cord to be stitched on by a seam through the braid, and which have no folding-guide,

the deliverybpening has been made adjustable to receive bra-id of different widths, and in some cases also a constant but yielding pressure has been exerted upon the braid by means of a spring. A corder has also been devised with atube made in twoparts connected by a springhinge, through which the covered cord passes to the sewing-machine; and, further, in order to allow cords of different sizes to pass,the presser-foot of the machine has been provided on the bottom with a groove, of which one side is formed by a plate adjustably connected with In the first of these cases, however, there is no folding-guide nor corddelivering means apart-from the tube. In the (No model.)

variable opening so place! that the cord is delivered into the fold made in the material by said guide, at least one of the devices between which the variable opening is formed being inclosed by the folded material.

The invention further consists in combining with the folding-guide cord-deliverin g means, which comprise a spring arranged to exert a yielding pressure on the cord, and also in the special combination of a folding-guide and a flat spring having its end recessed or spoonshaped, so as to partly embrace the cord.

The accompanying drawings, which form a part of this specification, illustrate corders embodying the invention.

Figure 1 shows in perspective a corder attached to the head of a sewing-machine. Fig. 2 is a perspective view from another position of the same corder detached from the machine,

and Fig. 3 an end elevation with the attaching-bar removed. Figs. 4 and 5 are perspective views, from somewhat different positions of a corder adapted to be attached to the clothplate of a scwii'lg-machine, and Fig. 6 an end elevation of the same. Fig. 7 is an enlarged detail view of the end of the spring which bears against the cord, and Fig. 8 a view of the spring detached.

A is afolding-guidc formed of a bent piece of metal with the ends turned inward, as shown at a. It is secured atone or both of said ends by soldering or otherwise to an upright plate, B, to which the end of a spring,C, is fastened by one or more screws or rivets or in any suit- 5 tween the spring 0 and the inner wall of said guide. The free end of the spring is provided with a shallow recess, oris made spoon-shaped, (see Figs. 7 and 8,) so as to retain the cord in the'middle of the folding-guide A and prevent it from escaping from the action of said spring.

Edge-guides b c are formed above and below the folding-guide, as in Figs. 1, 2, and 3, or a single guide, either above or below, can be used. In Figs. 4, 5, and G a lower guide only is represented. WVith the upper edge-guide, b. a spring-plate, 6, extending over the top of the folding guide, is employed to hold down the edge of the fabric to which the corded strip is to be attached and prevent it from escaping over the top of the edge-guide. Such a plate is not needed with the lower edge-guide, as the latter, when in use. rests upon the cloth-plate ofthe sewing-machine; but it can be combined also with such a guide.

If it is desired to fold the edge of a wide sheet or piece around the cord, a space for the introduction of such edge, as shown atf, Fig.

6, is left between the plate B and one of they turned-in ends of the folding-guide A.

In order to attach the corder to the machine an attaching plate or bar, D, is employed. The attaching plate, Figs. 4, 5, and 6, is or may be made in one piece with the upright plate B, and is adjustably secured to the cloth-plate of the sewing-machine by means of'the thumbscrew E, which passes through the slot d.

' The attaching-bar, curved as shown, Figs. 1

and 2, is or may be soldered to the foldingguide, and is adj ustably secured by a set-screw, g, to the hanger F, which is itself adjustably attached to the head of the machine by the setscrew G passing through a slot, h, in the upper' end of the hanger.

The head and clothplate of at Davis sewingmachine are represented in Fig. 1; but the same means of attachment as therein shown, or means equivalent thereto, can be used with other machines.

The mode of using the corder is as follows: The attachment being adjusted in position on the machine, the strip or piece of cloth is properly introduced in the folding-guide A around the end of the spring 0, and the cord is inserted between the cloth and the free end of the spring, which holds it in the fold of said cloth. The spring, therefore, not only lays the cord in contact with the cloth, but it also assists the folding operation, retaining by its pressure the cloth in proper position in the foldingguide. The spring readily yields and adapts itself to the inequalities or rough places in the cord, always maintains a gentle pressure thereon, and laysit smooth and true. When a large cord is introduced it simply pushes the free end of the spring farther to the right, Figs. 3

and 6, the delivery-opening being thus enlarged to conform to the increased size of cord to be delivered. The corder is adjusted laterally to bring the seam at the proper distance from the cord. The edge or edges of the fabric or fabrics to or between which the corded piece or strip is to be sewed are guided by the edge guides, or, when the corded strip is to be sewed to the fabric at a distance from the edge of the latter, the fabric is passed under or over the corder, and is guided by the operator, with or without the aid of any ordinary or suitable guides.

In theforegoingdescription what is regarded as thebestmodeofcarryingtheinventionintoeffeet has been explained; but various modifications may be made without departing from the spirit of said invention, and parts of the invention can be used without the others. For example, the delivering-openingfor the cord, instead of being between the spring and the interior wall of the folding-guide, could be between the spring and a special support separated by a greater or less distance from said wall, or both the spring and support could be arranged'outside of the folding-guide. The spring-instead of acting directly on the cord, could be made to exert its pressure through an intermediate device. The enlargement and contraction of the delivery-opening for the cord, instead of being efiected automatically by the retraction and return of a spring, could be effected by a device adjustably held in position through a slot and set screw or equivalent connection with the frame of the corder. With such an adjustable device, or with an ordinary rigid tube, eye, or groove a spring capable of yielding and adapting itself to inequalities in the size of-cord could be combined. The cord could be delivered through a tube having the end split and adapted to exert a yielding pressure upon the sides of the cord.

Having now described the said invention and the manner of carrying the same into effeet, what I claim isi 1. A sewing-machine corder comprising, in combination with a folding-guide, cord-delivering means with variable opening placed relatively to the folding-guide, as indicated, so that at least one of the devices between which said variable opening is formed is inclosed by the material folded by said guide, substantially as described.

2. The combination of a folding-guide and cord-delivering means, as indicated, comprisingaspring arranged to exert a yielding pressure upon the cord as it is delivered, substantially as described.

3. The flatspring having its free end recessed or spoon-shaped, combined with the folding-guide, substantially as described.

In testimony whereof I have signed this specification in the presence ot'two subscribing witnesses.
